Just how influential is photographer Jeremy Cowart? Wi-Fi card manufacturer Eyefi recently named him the “most socially influential photographer” in the world. But for Cowart, the operative word is “social,” even more so than “social media.” His online efforts go well beyond using online sharing sites to simply promote his image and his work. He’s out to change the world.

Light is a precious commodity in close-up and macro photography. The closer you get to your subject, the more light you lose through lens extension. Move to within inches of the subject and your camera or body may block the existing daylight. Also, the closer you get, the more depth of field you lose, so it would help to stop down. All of this translates to a need for additional light—in other words, a supplementary light source. What’s more, when shooting live critters and wind-blown plants, we may also need that light source to freeze subject movement, or at least provide shutter speeds that are fast enough to contain movement. To meet these needs, I’ve often turned to a macro ringflash and, alternatively, a macro twin flash. An economical alternative is an LED ringlight.

It’s already been a busy summer for new bags, and more are on the way. Bags of all sizes, shapes and colors make a formidable pile on my office floor. One bag, however, has scaled the mountain of ballistic nylon, crossed the river of Cordura and bravely navigated the toothy crevices of YKK self-healing zippers to emerge as the frontrunner. Read on to find out what’s so hot about the new Tenba Packlite Travel Bag and BYOB system.

It’s been my experience that there are a handful of special objects in the world that have developed cachet or “mojo” and are emotionally appealing to people in various fields. Some of these unique items engage our interest because they’re otherwise unassuming objects which have become associated with unusual people or events. I think of the track shoes Roger Bannister wore on May 6, 1954 when he ran the world’s first sub-4 minute mile. I think of “Brownie” and “Blackie,” two of Eric Clapton’s Fender Stratocasters. The console Sam Phillips used in Sun Studios to record Elvis Presley, Johnny Cash, Jerry Lee Lewis, Carl Perkins, and Roy Orbison must drip with “mojo,” as does Pete Seeger’s banjo, no doubt.

Kudos, Pizza Hut. You’ve created a very funny fake public service announcement (PSA) warning about “The Dangers of Selfie Sticks.” The video, which is embedded below, is led by motherly narrator who, at first, praises selfie photographers.

There was a time when I’d avoid a zoom lens as much as I’d avoid a swarm of midges. But in the digital age, the zoom lens has taken on new purpose, at least for me. Midges, however, are still a pest that is best avoided—especially when you’re changing lenses. And if you’re out in a marsh shooting spectacular scenic views, the Canon EF 11-24mm f/4L USM lens gives you the needed range of focal lengths so you can reign supreme over any landscape, as you avoid changing lenses while sidestepping concern that those midges will infiltrate your camera.

Our Shutterbug Photo of the Day is this beautifully vibrant portrait of a peacock by Roger Becker. Becker is a talented, self-taught nature, wildlife and landscape photographer whose work was featured in the National Geographic photo book “Dawn to Dark."

Mobile is an adjective often used to describe photography made with smartphones but I can put a tiny Panasonic Lumix GM1 in my pocket and take a walk—mobilize, if you will—as easily as my iPhone and shoot some nice photos. Instead, let’s call it what it really is: Smartphone Photography.

For this month’s assignment, we asked you to think outside the box about winter photography. While photos of snowmen and sledding are nice, we were looking for images that captured the true splendor of the season’s power and beauty. We wanted to see photos of winter with a sense of wonder and you delivered. Here are our nine favorite images of winter from Shutterbug readers.
